Manchester City have agreed terms with Arsenal for midfielder Samir Nasri, with the 24-year-old set for a medical.

Nasri trained with Arsenal on Tuesday morning ahead of the club's Champions League qualifier against Udinese on Wednesday, but has been omitted from the squad for the match.

The France international has arrived in Manchester to finalise a deal, worth a reported £25m to the Gunners.

Nasri is in the final year of the Arsenal contract he signed in 2008.

"The summer was very difficult because we had Fabregas and Nasri in permanent transfer negotiations and that is draining in the end," said Arsenal manager Arsene Wenger.

"We lost two great players and that's a sad side of the story. But at some stage it has to be over because you want to focus on the future."

City boss Roberto Mancini said on Sunday that he hoped to complete the deal within 48 hours.

Analysis

"Samir Nasri is a real top player and would be another quality signing for Manchester City. Roberto Mancini normally plays with two holding midfield players so he will be delighted to have someone who will add creativity alongside David Silva, Sergio Aguero and maybe even Carlos Tevez if he stays.

"I don't think Mancini will worry too much about where Nasri is going to fit in. He will simply want as many top-class players as possible and use them to suit the occasion. Nasri is a fluid player who can play across midfield anyway and Mancini will see it as another quality addition which underlines the fact City will be making a real challenge for the title."
